LT-4 Fuel pressure
What's the stock fuel pressure for an LT-4?
I'm running lt-4 stock injectors on my modded '86... running VERY rich (eyes tear from exhaust quickly) and it's at like 42 or 44 psi

If I remember correctly it's 43-45lbs, so it sounds like you're running the proper pressure for those injectors. Those injectors were rated at 28 lbs, and I believe your stock injectors were rated at 22 lbs. Have you hooked a scanner or any tuning software up to get an idea of the AFR?
